• Students, what features would you like to see on Windows 12?

  1) a scientific calculator with history and variables with a UI similar to https://sourceforge.net/projects/alt1-calculator/ that also can do units like https://qalculate.github.io/ 2) a tiny text chat direct message program that is similarly as easily accessible at Atl1 3) a minimalist dock of as many instances you would like similar to https://punklabs.com/rocketdock, and like where WIN opens the start menu, WIN...

• Paint on Windows is getting layers and transparency support

  Qalculate is my go-to for cross platform calculator that is useful and is not limited to the most basic +-*/ operations. https://qalculate.github.io/. - Source: Hacker News / 8 months ago

• Keisan Casio is shutting down

  If you want a self-hosted replacement for Keisan I strongly suggest looking at Qalculate! https://qalculate.github.io/. - Source: Hacker News / 9 months ago

• GNU Units

  I personally use Qalculate (https://qalculate.github.io/), specifically their CLI version for this purpose. I'm not sure how well it compares to GNU Units, but it works well enough for my needs; and it's fairly simple using English-like syntax. - Source: Hacker News / 10 months ago

• Ask HN: Do you still use a hand held/desktop calculator?

  On the terminal, I use `qalc`[1]. It's a nice natural language calculator that does arithmetic, solves quadratic equations/linear systems, does unit conversions and even a bit of calculus. Combine it with a cli graphing tool and you can do pretty cool things. Anything more complicated I'm probably ok with latency, so I open up wolframalpha and enter it there, again, in natural language. [1]... - Source: Hacker News / 10 months ago

• I'm writing a new vector search SQLite Extension

  Could this be implemented in Rust? Does that project (sqlite-loadable-rs) support WASM? https://observablehq.com/@asg017/introducing-sqlite-loadable-rs. - Source: Hacker News / 15 days ago

• Show HN: An extension to track your Wikipedia adventures

  Have you tried out a tangled-tree visualization? [1] I've found it to be super useful when visualizing these sorts of relationships in a compact way. [1] https://observablehq.com/@nitaku/tangled-tree-visualization-ii. - Source: Hacker News / 15 days ago

• A feature-rich front-end drag-and-drop component library

  Maybe I'm easy to impress, but I always stop and play around with the nested tree example when I come across Sortable. It works so flawlessly, and feels very tuned to mobile dnd. It even works to arrange (and reflow) inline spans in a paragraph! I have yet to come across this functionality in a text editor..

• Parquet-WASM: Rust-based WebAssembly bindings to read and write Parquet data

  Arrow JS is just ArrayBuffers underneath. You do want to amortize some operations to avoid unnecessary conversions. I.e. Arrow JS stores strings as UTF-8, but native JS strings are UTF-16 I believe. Arrow is especially powerful across the WASM <--> JS boundary! In fact, I wrote a library to interpret Arrow from Wasm memory into JS without any copies [0]. (Motivating blog post [1]) [0]:... - Source: Hacker News / 25 days ago

• A flat map with the least error possible: The Gott-Goldberg-Vanderbei projection

  Here’s the D3 implementation (which is just an interrupted azimuthal equidistant projection): https://observablehq.com/@d3/azimuthal-equidistant-hemispheres. - Source: Hacker News / 26 days ago
